Bradley Window Mastic

About our window mastic in Bradley
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you’re dealing with rushed sealant from a window installation and hard, cracked sealant around windows, we can put it right, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Bradley is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You get a one-year guarantee, the same in Bradley as everywhere else we work.

Surface by surface
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall and tooled smooth.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal. Neutral-cure sealant is the safe choice.
More services for Bradley
Do you need window mastic in Bradley?
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. Backing rod sets the right depth.
Most people get in touch after spotting something like this:
- Draughts coming in around windows and doors
- Gaps left after new windows were fitted
- Old mastic that has gone black or come away
- Gaps where the sill meets the wall
Around Bradley, as everywhere, window mastic is only as good as the preparation behind it.

What affects the cost of window mastic
We quote each job individually. This is what makes a difference:
- The number of rooms or windows
- Access and height
- How much there is to do
- Whether there’s mould to deal with
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Pictures of the joints, sent by email
- Roughly how big the job is
- Where the property is
- The problem you’ve noticed
Want a quote for window mastic? Please phone 0345 464 0079 or email us and tell us about the job. We will explain what we’d do and give you a clear price before any work starts.
The process
There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Bradley, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

What window mastic looks like in Bradley
Historic houses like Hall Place (about 1.9 miles south-east) are a reminder that the area around Bradley has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Bradley is about 5 miles west of Alton, in Hampshire. Whether you are in the middle of Bradley or further out, window mastic is available for homes and businesses alike, from flats and houses to offices and hotels. 683 places in Hampshire are on our list.

What happens if it’s left?
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Older cottages and farmhouses around Bradley can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. We will tell you how long your job needs when we quote.
Do the sealants smell?
There can be a smell while the sealant cures. Ventilation helps.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.
